This Bucket or Utility De-Icer uses multiple thermostats for efficient operation. Suitable for up to 30 gallon. The low-profile, finned design provides a large surface area, allowing the De-Icer to run cooler while putting out the same amount of heat as conventional De-Icer. This helps reduce the amount of mineral buildup and extend the life of the unit. Can be used in plastic containers. Durable, coated-aluminum base. 6 feet cord with anti-chew protector. Lock N Dry compatible.
